As Wez pointed out, this is almost ready to insert into the parser. Most of yesterdays conversation was spent hashing out the ways that this should be implemented.
Remember, one of the biggest reasons for creating this function was so that E_NOTICE would not be issued when attempting to read a variable that may or may not exist.
$x = ifsetor($_GET['foo'], 0);
An expression CANNOT be allowed for the first argument - because you cannot check to see if an expression isset().

Ok, missed that one, I never used multiple arguments to isset ;-)
Let's call it ifsetor, ifset or default then. But I still think allowing a list of expressions is a good idea because both
$a = ifsetor($db->get('x'), 'default_x');
and
$a = ifsetor($_REQUEST['x'], $db->get('x'), 'default_x');
make perfect sense IMHO.
